Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of round baling machines, in particular to a double compression chamber device for a round baling machine with non-stop function and the round baling machine. BACKGROUND

[0002] With the continuous optimization and upgrading of China's agricultural industrial structure and the rapid development of animal husbandry, the demand for forage grass is increasing year by year, and the utilization rate of crop straw resources is also steadily increasing. Under this background, the collection, storage and transportation of straw and forage grass put forward higher requirements for mechanized equipment. At present, China's straw and forage grass harvesting operation mainly uses square bale balers and round bale balers.

[0003] The existing round bale baler generally adopts a single compression chamber structure, and needs to stop during the operation to complete the net winding and bale unloading processes. Specifically, when the compression chamber pressure reaches the preset threshold, the device needs to stop moving, and the pickup mechanism needs to be temporarily stopped, and the net winding device needs to be started for net winding operation. After the net winding process is completed, the bale is released, and after the bale falls to the ground, the compression chamber rear door is closed, and the next working cycle can begin. This intermittent operation mode leads to relatively low working efficiency of the device. In addition, the traditional fixed-diameter round bale baler has the problem of uneven distribution of bale density, which is manifested as tight outer layer and loose inner layer, resulting in low overall average density of the bale.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0022] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or are the orientation or positional relationship in which the product of the application is usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0023] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0024] In the description of the embodiments of the present application, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0025] According to a first aspect of the present invention, there is provided a double compression chamber device for a round bagging machine with a non-stop function, such as Figures 1 to 8 As shown, the double compression chamber device for the round baling machine with the non-stop function is used for collecting and baling materials such as straw or forage grass. The double compression chamber device for the round baling machine with the non-stop function includes a main body 1 and a first compression chamber 2 and a second compression chamber 3 located on the main body 1.

[0026] In the following description, reference will be made to Figures 1 to 8 The detailed structures of the main body 1, the first compression chamber 2 and the second compression chamber 3 of the double compression chamber device for a round bag machine with a non-stop function are specifically described.

[0027] like Figure 1 As shown, in this embodiment, the main body 1 can be understood as the frame structure of the device, used for mounting and connecting the first compression chamber 2, the second compression chamber 3, and the feeding mechanism 4. At the same time, the device can also be installed on a round bagging machine through the main body 1. The shape of the main body 1 can be adjusted according to the specific structure and specifications of the round bagging machine, and is not limited here. As long as it can accommodate the first compression chamber 2, the second compression chamber 3, and the feeding mechanism 4 and achieve the purpose of packaging materials, it will be sufficient.

[0028] Specifically, the two ends of the main body 1 are respectively provided with a first compression chamber 2 and a second compression chamber 3. The two ends here can be understood as Figure 1 The left and right ends of Figure 1 This is a side view of the dual-compression chamber system for a round bagging machine with a non-stop function. From a top-down perspective, the first and second compression chambers 2 and 3 can be located at the front and rear ends of the actual process, respectively. The first compression chamber 2 performs pre-compression and pre-wrapping, while the second compression chamber 3 performs compression and bagging. The second compression chamber 3 performs bagging without affecting the first compression chamber 2's subsequent pre-compression.

[0029] Furthermore, a feeding mechanism 4 is provided at the bottom of the main body 1. This feeding mechanism 4 may include a picker commonly used in existing round-baking machines for collecting material, as well as conveyor rollers and forming belts for conveying material into the compression chamber. Since these components are commonly used in the prior art and are well known to those skilled in the art, their structural principles and installation methods will not be further described. The feeding mechanism 4 can pick up and adjust the size of the material, and then convey the material to the first and second compression chambers 2 and 3. The internal structure of the first and second compression chambers 2 and 3 can be similar to that of the compression chambers of conventional round-baking machines. For example, in this embodiment, the structure within the first compression chamber 2 (such as the conveyor rollers described below and the baling net feed rollers in the net winding mechanism) can be fixedly mounted within the first locking portion 201, while the second locking portion 202 may be installed with no specific structure or only with a portion of the fixed rollers used to secure the forming belts, to ensure smooth compression and packaging. However, this is not limiting and can be configured as needed, which is not a limitation here. The packaging and compression process of the double compression chamber device for the round bale machine with a non-stop function is the same as that in the prior art (for example, using a starting roller to form the material into a bale core, and then cooperating with a forming belt to form the bale, the installation of the forming belt can use a plurality of fixed transmission rollers to realize the driving of the material, and the hydraulic tension arm and other structures are close to the forming belt so that the bale can be compacted). These are all prior art and can be known to those skilled in the art. In addition, they are not related to the core design points of the present application scheme and can be found through inquiries on the Internet or existing patent documents, so they will not be repeated here.

[0030] The design difference between the double compression chamber device for round bagging machine with non-stop function and the compression chamber in the existing design is that the material pre-processed in the first compression chamber 2 can be pushed into the interior of the second compression chamber 3. Specifically, the first compression chamber 2 can include a first buckle portion 201 pivotally arranged at the first end of the main body 1 and a second buckle portion 202 coaxial with the feeding mechanism 4. The first buckle portion 201 can be around Figure 2 The first rotating shaft 203 shown in FIG. 1 rotates, and the second buckling portion 202 can rotate around Figure 2 The second rotating shaft 102 shown rotates, and the second rotating shaft 102 can also be the central axis of the feeding assembly 401. Driven by the rotation of the first snap-fitting portion 201 and the second snap-fitting portion 202, the material inside the first snap-fitting portion 201 and the second snap-fitting portion 202 is pushed into the second compression chamber 3. The second compression chamber 3 may include a third snap-fitting portion 301 pivotally arranged at the second end of the main body 1. The second compression chamber 3 can also be understood to be composed of the main body 1 and the third snap-fitting portion 301, and the third snap-fitting portion 301 can rotate around the second end of the main body 1. Figure 2The third rotating shaft 103 shown rotates, discharging the bales formed in the second compression chamber 3. The core operating principle of this dual-compression chamber device for a round-baling machine with a non-stop function is as follows: material enters the first compression chamber 2 through the feeding mechanism 4 for initial packaging. The material is then pushed into the second compression chamber 3 by the pivoting of the first and second locking portions 201, 202 to form a bale. The bale is then transferred to the wrapping mechanism 6 via the third locking portion 301, which wraps the bale. The wrapping mechanism 6 then releases the bale after the process is complete, completing one operation. Furthermore, since the material is pre-processed and compressed in the first compression chamber 2, the mass and size of the initially formed bales are relatively small. The forming pressure of the bales can be adjusted based on the smaller size and mass to ensure uniform density of the initially formed bales. The initially formed bales then enter the second compression chamber 3, where they gradually transform into bales with larger mass and size. Therefore, the forming pressure can also be adjusted based on the larger mass and size to ensure uniform density inside and outside the formed bales. This solves the problem of existing fixed-diameter round bale machines with tight outer and loose inner baling density, resulting in a low average density of the bales. Furthermore, the wrapping mechanism 6 can be a mechanism known in the prior art, and its structure and principle will not be further described here.

[0031] The double compression chamber device for the round bale machine with the non-stop function can realize the simultaneous operation of the double compression chambers through the cooperation of the main body 1, the first compression chamber 2 and the second compression chamber 3. By utilizing the pre-treatment of the first compression chamber 2 and the shaping and baling of the second compression chamber 3, the picking, net wrapping and material discharge can be realized without stopping the entire operation process, thus solving the problem of low equipment working efficiency caused by the intermittent operation mode in the prior art; in addition, the secondary baling operation of the first compression chamber 2 and the second compression chamber 3 solves the problem of low average density of the bales caused by the existing fixed-diameter round bale machine, which is tight on the outside and loose on the inside.

[0032] Preferably, if Figure 4 As shown, in the embodiment, a transfer port 101 is provided at the end of the main body 1 facing the first compression chamber 2, and the inner wall of the first snap-fitting portion 201 can abut against the inner wall of the second snap-fitting portion 202, so that the second snap-fitting portion 202 can surround the first snap-fitting portion 201, and the outer wall of the first snap-fitting portion 201 can abut against the transfer port 101 to separate the first compression chamber 2 and the second compression chamber 3.

[0033] Preferably, if Figures 1 to 5As shown, in this embodiment, a first web wrapping mechanism 501 and a second web wrapping mechanism 502 are respectively disposed on the top of the first locking portion 201 and the third locking portion 301. The first web wrapping mechanism 501 can pre-wrap the material within the first compression chamber 2, while the second web wrapping mechanism 502 can wrap the bales within the second compression chamber 3. In the first compression chamber 2, to ensure the density and quality of the pre-compressed bales, the first web wrapping mechanism 501 can be used to wrap the pre-compressed bales. Even if the material is relatively small, the first web wrapping mechanism 501 may be pre-set to wrap the bales in the first compression chamber 2. However, if the pre-compressed bales do not require web wrapping, the first web wrapping mechanism 501 can be disabled. In addition, it should be noted that the first web wrapping mechanism 501 and the second web wrapping mechanism 502 can both be web wrapping mechanisms commonly used in the prior art (for example, including an actuator, a mesh packaging system and a packaging net feed roller, etc., the bales are formed by contact with the packaging net feed roller, and the bales are wrapped with the forming belt in the above-mentioned compression chamber). The web wrapping mechanism and the web wrapping process are known to those skilled in the art, and the coordination structure with the compression chamber is also a common structure, which will not be repeated here.

[0034] Preferably, if Figures 1 to 5 As shown, in the embodiment, the ends of the first compression chamber 2 and the second compression chamber 3 facing the feeding mechanism 4 are provided with a first feeding port and a second feeding port (due to Figures 1 to 5 It is a side view, so the first feed port and the second feed port are not shown. The first feed port can be the end of the first snap-fit ​​portion 201 close to the feeding mechanism 4, and the second feed port can be the bottom of the main body 1 close to the feeding mechanism 4). The feeding mechanism 4 may include a feeding component 401 and a channel adjustment component 402. The feeding component 401 may be, for example, the picker mentioned above, for picking up materials. The channel adjustment component 402 is adjustable and arranged on the side of the feeding component 401 so that the material enters the first feed port or the second feed port through the feeding component 401. The channel adjustment component 402 may include an H-shaped structure (with Figure 1 As shown in the side view, one of the two vertical plates of the H-shaped structure is coaxial with the second rotating shaft 102. The two vertical plates of the H-shaped structure can be driven by the horizontal plate to move toward the first feed port or the second feed port as a whole, thereby moving the material entering from the feeding component 401 to the first feed port or the second feed port.

[0035] Preferably, if Figures 1 to 5As shown, in this embodiment, a density control mechanism is provided on the side of the second fastening portion 202 away from the first fastening portion 201. The density control mechanism may include a tensioning spring 7, which abuts against the outer wall of the second fastening portion 202. As the material inside the first compression chamber 2 gradually increases, the tensioning spring 7 is gradually compressed by the second fastening portion 202. The density control mechanism may also include a positioning seat for fixing the tensioning spring 7. The positioning seat may be fixedly mounted on the main body 1 in the form of a fastening bolt and a nut. The tensioning spring 7 is provided at the end of the fastening bolt.

[0036] Preferably, if Figure 4 As shown, in this embodiment, to ensure stable movement, the first fastening portion 201 and the second fastening portion 202 are connected by a connecting rod 8. The first end of the connecting rod 8 is rotatably connected to the second fastening portion 202, and the second end of the connecting rod 8 is provided with a sliding groove, in which the first fastening portion 201 is slidably disposed via a connecting member 9. Both ends of the connecting rod 8 can be connected to the first fastening portion 201 and the second fastening portion 202 via a connecting member 9, which can be, for example, a pin.

[0037] Furthermore, if Figures 6 to 8 As shown, in an embodiment, the double compression chamber device for the round bread machine with the non-stop function may further include a sensor 10 and a user interface 11. The user interface 11 detects the distance between the user and the outer wall of the second snap-fit ​​portion 202, i.e., the second gap 12, through the sensor 10. The sensor 10 may be, for example, a distance sensor, and the user interface 11 may be, for example, a display screen in the cab of the round bread machine. The length of the second gap 12 may provide feedback on the current state in the first compression chamber 2, and the user may understand the state in the first compression chamber 2 through the user interface 11.

[0038] The specific working process of the double compression chamber device for round bagging machine with non-stop function is as follows: preferably, Figures 1 to 5 As shown in the embodiment, the double compression chamber device for the round bag machine with the non-stop function can be switched among the empty state, the front compression state, the transfer state, the rear compression state and the discharge state. The empty state is as shown in FIG. Figure 2 As shown, the pre-compression state is as follows Figure 3 As shown, the transfer status is as follows Figure 4 As shown, the discharge status is as follows Figure 5 As shown, the difference between the post-compression state and the pre-compression state lies in the different orientations of the channel adjustment assembly 402. Specifically, when the dual-compression chamber device for a round bag machine with a non-stop function is in the empty state, pre-compression state, and discharge state, the channel adjustment assembly 402 faces the first feed inlet. When the dual-compression chamber device for a round bag machine with a non-stop function is in the transfer state and post-compression state, the channel adjustment assembly 402 faces the second feed inlet.

[0039] Preferably, if Figure 2 As shown, in the embodiment, when the double compression chamber device for a round bag machine with a non-stop function is in an empty state, the first fastening portion 201 is fastened to the second fastening portion 202, and the third fastening portion 301 is fastened to the end of the main body 1 facing away from the first compression chamber 2; at this time, the first gap 204 between the first fastening portion 201 and the second fastening portion 202 is in an empty state (which can also be understood as no gap), and there is a second gap 12 between the second fastening portion 202 and the sensor 10 (as shown in FIG. Figure 6 As shown, the length of the second gap 12 is calibrated to a zero position, and the user can see through the user interface 11 that the first compression chamber 2 is empty and no pressure is applied to the bale. At this time, the feeding port of the channel adjustment assembly 402 is connected to the first feed port.

[0040] Preferably, if Figure 3 As shown, in the embodiment, when the double compression chamber device for a round bag machine with a non-stop function is in the front compression state, the first buckle part 201 and the second buckle part 202 gradually separate. At this time, the bales inside the first compression chamber 2 gradually increase, causing the first buckle part 201 and the second buckle part 202 to gradually separate. The second buckle part 202 rotates counterclockwise around the second rotating shaft 102, and the tension spring 7 is gradually compressed. Figure 7 As shown, the second gap 12 gradually decreases until it reaches the set value. At this point, the sensor 10 receives a signal, causing the channel adjustment assembly 402 to change position and align the feed port with the second feed port. At this point, the first wrapping mechanism 501 begins to pre-wrap the bales inside the first compression chamber 2. The pre-wrap can be activated or deactivated as needed.

[0041] Preferably, if Figure 4 As shown, in the embodiment, when the double compression chamber device for the round bag machine with the non-stop function is in the transfer state, the first snap-fitting part 201 is separated from the second snap-fitting part 202, and the third snap-fitting part 301 is snap-fitted to the end of the main body 1 facing away from the first compression chamber 2. After the pressure in the first compression chamber 2 reaches the set value, the sensor 10 receives a signal, and the tensioning spring 7 releases the pressure, which can give the second snap-fitting part 202 an initial driving force to transfer the bale. The first snap-fitting part 201 can then be driven by the oil cylinder (not shown, which can be set on the main body 1) to open upward, driving the connecting rod 8 to move. The connecting rod 8 pulls the first snap-fitting part 201 to rotate clockwise around the second rotating shaft 102, pushing the bale into the second compression chamber 3. At this time, the second gap 12 is relatively large (such as Figure 8 As shown), the user can receive information through the user interface 11 that the first compression chamber 2 is in an open state or in the current transmission position.

[0042] Preferably, if Figure 5As shown, in this embodiment, when the dual-compression chamber device for a round bale machine with a non-stop function is in the discharge state, the first fastening portion 201 is fastened to the second fastening portion 202, and the third fastening portion 301 is separated from the main body 1. As the material increases, the pressure inside the second compression chamber 3 also increases. When the gap between the third fastening portion 301 and the main body 1 reaches a certain distance, the sensor 10 receives a signal, the channel adjustment assembly 402 connects the feed port with the first feed port, and the second web wrapping mechanism 502 wraps the formed bale. After wrapping, the third fastening portion 301 rotates counterclockwise about the third rotating shaft 103, and the bale rolls onto the film wrapping mechanism 6. The third fastening portion 301 then closes, and the film wrapping mechanism 6 wraps the bale. After the process is completed, the bale is released, and a cycle is completed. The entire process is non-stop.

[0043] The double compression chamber device for the round bale machine with the non-stop function can realize the simultaneous operation of the double compression chambers through the cooperation of the main body, the first compression chamber and the second compression chamber. By utilizing the pre-treatment of the first compression chamber and the forming and baling of the second compression chamber, the entire operation process can be realized without stopping, including picking up, wrapping and unloading, thus solving the problem of low equipment working efficiency caused by the intermittent operation mode in the prior art. In addition, the secondary baling operation using the first and second compression chambers solves the problem of low average density of the bales caused by the existing fixed-diameter round bale machines, which are tight on the outside and loose on the inside.

[0044] Furthermore, according to a second aspect of the present invention, there is provided a round bagging machine, which includes the double compression chamber device for a round bagging machine with a non-stop function as described above.

[0045] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them.
